Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a ...

This study demonstrates a passive metasurface technology that uses a time-varying mechanism with field-effect transistors to suppress multipath signal interference.

For something we rely on so heavily, GPS is pretty rubbish. In the open, it is accurate to within a few metres, but in built-up areas it frequently cannot even locate the correct city block. Now a new ...

This video presents a study in which researchers developed a passive metasurface that uses a time-varying interlocking mechanism with metal-oxide-semiconductor field-effect transistors to selectively ...
